Definitions
- the invention relates to a torsion beam axle for motor vehicles and a Process for producing a cross member therefor.
- Twist-beam axles combine the advantages of a simple structure small space requirement and good kinematic properties.
- the one cross member connecting lateral trailing arm acts as a torsion profile, so that with a simultaneous deflection a trailing arm characteristic and results in a semi-trailing arm characteristic with mutual compression.
- a torsion beam axle is known also has a cross-member V-shaped in cross section.
- the cross member is welded to the trailing arms via U-shaped transition pieces.
- a torsion beam axle belongs to the stand the technology with a V-shaped cross member, the top of which is up has.
- the legs are directed obliquely downwards.
- gusset plates are welded from the cross member to the trailing arms, which extend from the cross member towards the trailing arm provided wheel carriers extend.
- Such a twist beam axle has a high rigidity compared to forces acting laterally on the trailing arms.
- the welding of the gusset plates between cross member and the trailing arm leads to a increased manufacturing costs.
- the invention is based on the prior art Task based on a torsion beam axle ensuring a high performance to make it more efficient and a manufacturing process to show a cross member for a twist beam axle.
- twist beam axle has two connected by a cross member Trailing arm on, the cross member consists of a profile with a single-ply, partially open middle section, on which there are two sides Connect tubular closed ends.
- the ends can be round or be oval.
- the crossmember is generally tubular, but in the middle section open in some areas.
- the central section has an oval elongated section on (claim 2).
- the Middle section at least over the major part of its length essentially V-shaped or U-shaped cross-section provides.
- On the trailing arms are receptacles for the ends of the cross member trained (claim 4).
- the overall configuration of the torsion beam axle reaches one on the dynamic Loads coordinated design of the resistance moments.
- the V- or U-shaped cross-section in the middle section of the Cross member at.
- the torsion and bending forces are efficiently transferred from the trailing arms into the crossbeam acting as a torsion profile, in which the forces are reduced or compensated.
- Twist beam axle according to the invention a particularly good static and dynamic load behavior and achieves a long service life.
- a stiffness adjustment of the torsion beam axle can depend on the vehicle type be made by varying the thickness of the cross member. However, this is preferably done by twisting the cross member. Since the cross section of the ends is preferably round, the Cross member without twisting the component during assembly a twist experienced to change the driving characteristics depending on the vehicle variant. This is a rotational alignment of the cross member or central longitudinal axis running centrally through the legs of the central section in relation to the longitudinal axes running through the trailing arms.
- the particular advantage of this measure lies in the wide range of variations the parameter relating to the axis of gravity of the cross member to the roll center of the motor vehicle. In this way, the specific Driving characteristics of the motor vehicle with regard to roll stiffness as well as the adjustment of the track and camber on the wheel flange without a significant component change being necessary.
- a procedure according to claim 5 To produce a cross member is first a flat circuit board is manufactured, the geometry of which unwinds Cross member corresponds. The board is then shaped into a tube and the longitudinal edges of the ends of the cross member, which are then adjacent to one another added, preferably welded.
- the manufacture of the cross member is efficient and very easy to automate.
- the cross member as well as the entire torsion beam axle can both made of steel and light metal, in particular aluminum or one Combination of the aforementioned materials can be produced.
- the twist beam axle according to the invention or its manufacture comes with just a few manufacturing steps. After the board is welded to the tube the cross member is finished. Then this can also be used at the end the trailing arms.
- the invention leads to the saving of Costs because no expensive pipes have to be used as semi-finished products. Individual parts can also be saved, for example because of additional ones Gusset or transition plates in the connection area to the trailing arms omitted.
- FIG. 1 shows a twist beam axle 1.
- This essentially comprises two wheel-guiding trailing arms 2, 3 and one the two trailing arms 2, 3 connecting cross member 4.
- the Cross member 4 consists of a profile with a single layer in some areas open middle section 5, to each of which is closed on both sides in a tubular manner Connect ends 6, 7.
- the middle section 5 has an oval elongated Section 8 on. This results in the middle section 5 open cross-sections in V- or U-shaped configuration.
- On the trailing arms 2, 3 are suitable receptacles 9, 10 for the ends 6, 7 of the cross member 4 trained. The ends 6, 7 are fitted into the receptacles 9, 10 and joined, usually welded. This ensures good power transmission guaranteed by the trailing arms 2, 3 in the cross member 4.
- an output board made of metal, for example steel, aluminum or another metallic material provided. This receives a sheet metal trim so that its circumferential geometry the processing of the cross member 4 corresponds. Essentially the development is rectangular, being arched on the longitudinal edges running cuts 11 are present. The contour can be seen in the figure 3. The trimmed board is then shaped into a tube and the at the ends 6, 7 of adjacent longitudinal edges 12, 13 with one another welded. The weld seams are identified in FIG. 2 by 14, 15.
- the ends 6, 7 have a round closed cross-section, like that Figure 4 illustrates.
- the cross member 4 has a V or U-shaped open cross-section.
